Abstract
PURPOSE: To obtain a sufficient response property even in a transition time by a method wherein an alteration control of a parameter of a cross limit is effected in dynamic and feed forward type in a fuel control system for a combustion furnace by a double cross limit method.
CONSTITUTION: A combustion furnace is controlled so as to keep an internal porton thereof at the most suitable temperature by a method wherein a signal obtained by a thermocouple 2 attached to a furnace wall 1 is transduced into a temperature signal by a transducer 4 to output it to a temperature adjusting meter 5 and an operation signal SV obtained here is outputted to respective flow control valves 7, 10 through an operation control section 12 adopting double cross limit method, fuel and air flow adjusting meters 13, 14. In this case, said operation signal SV and the fuel flow signal PV are inputted into a deviated value measuring section 123 and when the deviation has become bigger than a given value, parameters K1WK4 of the double cross limit are altered into values K1'WK4' dynamically. The parameters K1'WK4' are altered properly in accordance with a variable G, outputted from a function generating section 124, and response correcting signals a1, a2 of the fuel and air flow.
